I star-awn or Letters Patent No. 2, 99, dated Jul 2, 1842.

To all whom it mayconcem:

Be it known that LIMOsfis BARTHoLoMEW, of Vershire, in the county ofOrange and State of Vermont, have invented an Improved Cooking.-St'ov'e,.in which ,Either lVood'or Coal May be Used as Fuel; and I dohereby declare that the following is a full and exact descriptionthereof.

My stove, which I denominate the conjoined furnace stove, is constructedwith two separate fire chambers, or furnaces, which I will call thefront and rear fire chambers, or furnaces, in either of which a fire maybe made separately; the rear furnace is further capable of being dividedinto two by means of a swinging partition, and thus admitting of a firebeing made in one half of the rear furnace, or fire chamber, only. Iusually employ three boilers, or other cooking utensils, in my stove,one of them, which may be of a large size, over the front, and two overthe rear fire chamber. There is not any oven in the body of my stove,but I combine therewith, in the rear of the rear fire chamber, an 1elevated oven, constructed in a manner very similar to the elevatedovens previously used.

In the accompanying drawings, Figure 1,

l is an end view of my con oined furnace stove.

A, is the body of the front fire chamber, and B, the body of the rearfire chamber; these two being combined with each other by means of thetop plate C, C, shown more distinctly in Fig. 2, which is a top view ofthe stove. The interior of the front fire chamber is shown at D, andthis may be used with wood as fuel, or it may be furnished with a grateadapting it to the burning of coal.

E, E, Figs. 1, and 2, is the interior of the rear fire chamber, seen, inFig. 2, through the two boiler holes.

F, is the bottom plate of the fore fire chamber, constituting, also, itssunk hearth.

G, is the bottom plate, or hearth, of the rear fire chamber. The dottedlines a, a, in Fig. 2, show the place of the front and back plates ofthe rear fire chamber; this chamber is capable of being divided into twoparts by a swinging partition shown by the dotted lines b, 7), and whichmay be turned by means of the handle a, so as to stand across the centerof the fire chamber,

thus dividing it into two parts; or to lie against its back plate,constituting it a single fire chamber. In Fig. 3, which is a ver- 1tical cross section through the middle of the rear fire chamber, H, isthe swinging partition represented as crossing said chamber, anddividing it intotwo parts.

The boiler openings are surrounded by elevated collars I, I, as inStanleys rotary, and some other, stoves; and the front and rear firechambers are connected together by flue spaces, J, J, formed in the topplate C, C, in a manner well known.

K, K, are similar flue spaces in the rear of said top plate which leadfrom the rear fire chamber to the elevated oven fiues, or pipes, L, L;the top plate C, being continued back for that purpose. In Fig. 2, thepipes L, L, are removed, the valves cl, cl, which they contain beingshown.

Fig. 4, is the back end of the stove, the

back plate B, B, being shown as cast with.

a double swell, but it may be flat, if preferred.

M, is the elevated oven, which is constructed in the usual manner,excepting that I make one or both of its heads, or ends, to open bymeans of a hinge, so that the flue space may be completely exposed, andreadily cleaned.

N, is the hinged head, and O, the ordinary oven door.

In using this stove, a fire maybe made in the fore fire chamber only,and the heated air will pass from it through the fiues J, J, to theelevated oven. When the large boiler is not wanted, a fire may be madein the rear fire chamber only, and the two rear boilers, and theelevated oven be thereby heated; or a fire may be made in one half ofthis fire chamber, and the heat be confined to one boiler. When thelarge boiler in the front, and one of the rear boilers only is wanted tobe used, by closing the damper in one of.

the pipes L, and leaving the other open, the partition H, being allowedto cross the stove, this end will be attained.

Having thus fully described the manner inwhich I construct and use myconjoined furnace stove, what I' claim therein as new, and desire tosecure by Letters Patent, is

1. The particular manner in which I have combined and arranged theperspective parts thereof, as herein set forth; that is to say, I claimthe combining of the fore and rear fire chambers, or furnaces, by meansof a top plate furnished with elevated collars, and with fiues, J, andK, formed therein for the passage of heated air from the fore to therear fire chamber, and to an elevated oven; the rear fire chamber, also,being provided with a swinging partition, by which it may be dividedinto two parts, in the manner, and for the purpose, described.

2. I claim, also, the manner of constructing an elevated oven with oneof its heads hinged to the exterior case of said oven, by which meansthe flue space is completely exposed, and may be readily cleaned. And itis to be distinctly understood that I do not'claim the combining in onestove of two separate furnaces, in either of which a fire may be made atpleasure, as in itself new, 5

such a stove to the particular manner of 2c combining and adapting therespective parts thereof substantially in the manner herein made known.
